  • Title: [The realization of tracking power-line interference adaptive coherent model base on part FFT].
    Author: Yu C, Li G, Lin L.
    Journal: Sheng Wu Yi Xue Gong Cheng Xue Za Zhi; 2007 Aug; 24(4):780-4. PubMed ID: 17899744.
    Abstract:
    Adaptive coherent model can be easily implemented and it can simultaneously reject the power-line interference and baseline wander. But the relevancy of the filter's bandwidth at low-frequency and power-line interference limits its application on ECG filtering. A part fast Fourier transform (FFT) algorithm is presented. It is used to track power-line frequency and adjust the sample frequency. Experiments show that the method still rejects interference efficiently despite of the slow fluctuation of power-line frequency.
